Gas permeability properties of decorated MCM-41/polyethylene hybrids prepared by in-situ polymerization

▸ Several approaches are checked for decorating MCM-41/PE hybrids. ▸ Effective interactions between UA/TIBA with the silanol surface groups of the MCM-41 are detected. ▸ Incorporation of MCM-41 increases permeability of O2, N2 and CO2 compared with those for HDPE. ▸ Membranes are prepared by melt compression, an attractive protocol from industrial standpoint.
